AT90PWM216-16SE ATMEL [ATMEL Corporation], AT90PWM216-16SE Datasheet - Page 259

• Manufacturer Part Number: AT90PWM216-16SE
• Description: 8-bit Microcontroller with 16K Bytes In-System Programmable flash
• Manufacturer: ATMEL [ATMEL Corporation]

7710D–AVR–08/09
Warning: Always clear AMPnTS0:1 when clearing AMPxEN
• Bit 6– AMP1IS: Amplifier 1 Input Shunt
Set this bit to short-circuit the Amplifier 1 input.
Clear this bit to normally use the Amplifier 1.
• Bit 5, 4– AMP1G1, 0: Amplifier 1 Gain Selection Bits
These 2 bits determine the gain of the amplifier 0.
The different setting are shown in
Table 21-10. Amplifier 1 Gain Selection
To ensure an accurate result, after the gain value has been changed, the amplifier input needs
to have a quite stable input value during at least 4 Amplifier synchronization clock periods.
• Bit 1, 0– AMP1TS1, AMP1TS0: Amplifier 1 Trigger Source Selection Bits
In accordance with the Table 21-11, these 2 bits select the event which will generate the trigger
for the amplifier 1. This trigger source is necessary to start the conversion on the amplified
channel.
